BOILER FOR DOMESTIC PURPOSES.

SPECIFICATION forming part of Letters Patent No. 251,518, dated December 27, 1881. Application filed August 19, 18 81. (No model.)

To all whom it may concern:

Be it known that I, ELISHA P. BRYDEN, a citizen of the United States, residing in the town of Guilford, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Boilers, of which the following is a specification.

My invention relatesto boilers designed more especially for-domestic purposes, and the object of my invention is to provide a convenient boiler for domestic purposes; and it consists in the combination of parts hereinafter de scribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an isometlical representation of a tub embodying my invention, of which Fig. 2 is a plan view, in which a portion of the upper plate of the heater is broken away. Fig. 3 is a transverse vertical central section on dotted line 00. Fig. 4 is an isometrical inner face view of the metallic stave.

The vessel or tub represented in the accompanying drawings is of the usual form, having its side walls composed of staves, and a bottom fitted in a groove formed in the end portion of the staves, which are bound together by suitable hoops.

In my improvement the staveslrepresented at A) are of wood, and in this instance their edges are grooved, as at a, to engage each other, and near one end thereof are provided with a groove, as at b, to receive theedge portion ofrthe bottom B. -One stave, however, necessary to complete the outer wallof the vessel, as represented at (J, is preferably made of cast-iron, having its edges grooved, as at c, to engage the grooved edges of the wood staves, and its end grooved at d to coincide with the and grooves, 11, of the wood staves, provided to receive the bottom B, the edge of which is fitted to engage the groove. These staves and bottom are securely bound together to produce a water-tight vessel by means of sufficient hoops. (Represented at e.)

The metallic stave O is provided with an opening, as atf, to admit fuel to the fire-box. The edge portion of this opening, on all sides thereof on the inside of the stave, is provided with perforated flanges h, projecting in ward to receive the end portions of the walls '5 of the fire-box D. This metallic stave is also provided with a perforated outside vertical flange, k, the ends of which connect with the ends of the horizontal flanges of the fire-box, and is designed to receive the end portion of the vertical outer wall of the heating-chamber E.

The outer walls of the heater and fire-box, consisting of the top l, bottom m, the straight vertical edgewall, n, and the curved edge wall 0, are made from any suitable plate material, having the edges at their angles suitablyjoined to produce water-tight seams or joints. The end portions of these walls of the fire-box and heater are securelyfixed, by rivets or otherwise, to the outer flanges, h and 7c, of the opening f in such a manner as to produce a water-tight connection.

Atp is represented a vertical division-wall employed to separate the fire-box from the heatin g-chamber, havingits outer end fixed, by riveting or otherwise, to the central vertical flange, h, which separates the heating-chamber from the fire-box. The edges of this division-wall are fixed'in any suitable manner, by rivets or otherwise, to the bottom and top walls of the fire-box and heatingchamber. It however does not extend entirely through the heater, but stops short thereof, forming an opening,p, between its end and the curved vertical wall of the heater, to permit the products of the combustion not otherwise utilized to pass from the fire-box into the heating-chamber and the unconsumed gases to return through the heating-chamber and escape through the vertical smoke or gas pipe.

At 12 is represented a damper, fitted to slide in grooved ways lengthwise of the divisionwall to close the opening p, which connects the heating-chamber with the fire-box. This damper is provided with a rod-stem extending outward through the metallic stave, as at s, by means of which the slide may be operated to regulate the draft by varying the size of the opening 1). The metallic stave is fitted with an opening, 8, which connects with the heating-chamber, and on the outside of the stave is fitted with a collar adapted to receive a suitable pipe, as represented at F, through which to permit the unconsumed gases to escape.

At t is represented a grate, suitably supported in the fire-box, on which to place the fuel.

At a is represented a door, hinged to the metallie stave in position to close the opening in the stave, as a door to the furnace. This firebox and heater is supported in the vessel or tub, some distance from its bottom, on suitable supports, to permit the water contained in the vessel to surround it on all sides, except the end fixed to the metallic stave.

In use the water to be heated is placed in the tub or vessel in contact with the walls of the fire-box or heater. Fire is then kindled or started upon the grate in the fire-box, and the heat produced thereby is rapidly imparted to the water.

My improved boiler will be found a valuable article for domestic purposes, particularly for the purpose of washing in domestic practice, and also in laundry practice, in which the articles are placed in the water in the boiler and kept hot during the process of washing. It will also be found a valuable improvement in the dish-washing room of restaurants, hotels, and other similar situations for the purpose of washing dishes and other table articles, and it is capable of use for other purposes which require rapid economical boilers.

I claim as my invention- 1. A tub or other vessel provided with a metallic stave grooved to fit the adjacent staves of the vessel, and provided with a fuel-opening and a small opening near the latter to admit of the passage of the products of combustion to a smoke-flue, both of said openings being surrounded on the inner side of the stave with perforated flanges to receive the fire-box and heating-chamber, substantially as setforth.

2. The combination, with the wooden staves of a tub or other vessel, of a metallic stave formin g a part of the vessel, and provided with the openings, as described, the latter being surrounded on the inner side of the staves with flanges, which are perforated to receive the end of a fire-box and heating-chamber, substantially as set forth.

3. The combination, with the Wooden staves ofa tub or other vessel, of a metallic stave forming a part of the vessel, and provided with the openings and inwardly-projecting perforated flanges, the fire-box D, heating-chamber E, and vertical division-wall 19, substantially as setforth.

4. The combination, with a tub or other vessel, of a metallic stave having the fuel-opening and smoke-flue opening both surrounded by perforated flanges on the inner side of said stave, a fire-box and heating-chamber, partition 1), and damper h, substantially as set forth.
